prerequisite for effective optimization
ANSA pre-processor and META post-processor in combination with all popular optimization codes,
provide a complete tool for optimization applications.
From concept design to final testing, ANSA & META package brings enormous performance and
versatility to the optimization problem set-up.
The ability to control the model shape using the ANSA Morphing Tool, ANSA model values and even
complicated tasks such as batch meshing and model checking, makes the tool unique.
Morphing features
- Shaping of FE model through the use of 3D, 2D, 1D and Cylindrical
boxes
- Morphing on CAD geometry
- Morphing Parameters to control model shaping in a parametric way
- Parameterizing any manual morphing operation by the
DEFORMATION parameter
- Accurate morphing of model feature lines by fitting on target curves
- Recording of morphing states for easy recovering of any previous
shape
- Automatic reconstruction to improve mesh quality after morphing
- Special entities, called Nested Elements, to constrain the shaping of
specific features of the model such as holes and beads
Direct Morphing
- A powerful new morphing algorithm performs direct morphing on
geometry or FE model without the need of morphing boxes. This
process minimizes the set up time especially in large models
- Direct morphing can be applied by means of edge fitting or Control
Points movement
- Depressions and simple features definition
- Parametric control of holes diameter
- Cross section morphing
Process automation
The integrated process automation tool facilitates the set up of the
optimization sequence. Design variables are defined in the
Optimization Task and are connected with any Morphing Parameter
and thus control the shape modifications of the model. In a similar
manner Design variables are connected and control any parameter of
any ANSA entity (shell thickness, material density, spotweld distance,
etc.). Furthermore, complicated actions, such as features creation and
treatment, parts replacement and mesh quality improvement are
assigned to the process and driven by design variables.
Coupling with optimizers
- Direct coupling with LS-OPT, modeFRONTIER and OPTIMUS, without
the need of any scripting
- Coupling the Optimization Task with any other parametric optimizer,
such as Isight and DAKOTA, without the further need of scripting
- Integrated TOSCA Structure interface which is able to define
Topology, Shape and Bead optimization scenarios
- Automatic meshing quality improvement of the optimum model
and automatic definition of the validation model after TOSCA Run
- Monitoring the TOSCA Run through the ANSA Interface
prerequisite for effective optimization
Simulation and model validation
- A special tool to simulate and animate the model shape for
different combinations of design variable values gives the user the
ability to check the model before contacting with the optimizer
- Video recording of the animated model
- Enhanced Design Of Experiments, Full Factorial Algorithm for easy
definition of experiments
- Definition of full model reports during the optimization process
checking model validity
- Automatic model fixing, such as property thickness penetration, is
performed during the optimization loops
Spotweld optimization
- Parametrization of weldings and easy handling by the Optimization
Task
- Control parameters such as spotweld distance, number of
spotwelds, spotwelds' diameter, connections' properties or
materials, and alternative connections representation types
- Combined spotweld and Shape Optimization Morphing Tool can
handle Connections Points, Lines and Faces in the same way as the
Morphing Tool can handle Connections Points, Lines and Faces
- Distribution and control of spotwelds by defining connection density
function along the connection line

prerequisite for effective optimization
Multidisciplinary optimization
- A defined optimization sequence can be applied on different
representations of the same model and prepared for different
solvers and analysis scenarios for the set up of multidisciplinary
optimization problems
- The use of common Optimization Task and Morphing Boxes in
different analyses ensures the identical shaping
Post-processing
- A special tool in META offers a flexible way for the responses and
histories extraction, from the solvers result files
- Responses extraction from the 3D model and the 2D Plot
- The automatic definition of postprocessing sessions to participate in
the optimization loop, and the calculations upon solvers results, are
only a few of META's powerful capabilities
NASTRAN SOL 200
- Support of the required keywords for the definition of NASTRAN SOL
200 cases for property, and material optimization
- Use of the Morphing tool for the massive definition of the DVGRIDs for
shape optimization according to the Manual Grid Variation method
- Support of the keywords TOPVAR, TOMVAR and BEADVAR for
topology, topometry and topography optimization
